1 Uncia Wheel / Wheel, four straight spokes

The wheel symbol on cast bronze from this period is generally associated with Etruscan production, though the precise mint responsible for this series remains unattributed — a situation unlikely to change given the near-total absence of archaeological findspot documentation for most surviving specimens. What is clear is that the uncia denomination places this at the twelfth part of the as, the lowest practical division in the Etruscan cast bronze system at a moment when Rome's own aes grave was still the dominant monetary framework in central Italy.
